Pete McCarthy book states the intake was a non production intake. In another book I have read, the book makes mention to the intake having cold start issues. When pontiac was conceiving this engine in 71 the emissions were not as restrictive. I have a 72 trans am. It was a transitional year and even at that my car would not pass 73 emission and bumper regulations. That is why so many cars had to be scrapped after the 72 strike. No one is saying this intake came on any super duty production car. It may be one of the few they were trying on the prototype engines and when the higher ups said no because of cost concerns they did not want to throw them away so they probably put them on early 72 T/A's. When this intake warmed up after a couple of minutes it was awesome with the 455. If you were going to make an all out race engine like the super duty do you think if the engineers had there way they would have preferred an aluminum intake which is considerably lighter,more than likely. They had success with the 71 HO intake. I have had guys email me and said they remember being able to buy this intake from the GM parts dept. There are too many people out there that seem to have knowledge about this intake to simply dismiss it. It's just like the turn signal lens on the 72 trans am. My car is an early one and has clear lights. The car was made in 71. Cars made in 72 seem to have the amber lens. Looking at my data tag, my car started as a base firebird and was used in building a trans am. It is an early Trans am. Things changed quickly back then and people made the best with the cards they were dealt with. Who is to say for sure who is right. I think it is an interesting subject. We should all keep an open mind.
